2 Claims.

My invention relates to an interchangeable combined cap and dispenserfor jars and the like, adapted to be attachable to an empty jar havingviscous contents therein, particularly to cosmetic cold cream jarshaving an inner tapering Wall portion.

One of the important objects of my invention is in the embodiment of adouble cap arrangement, in which the outer plastic member is providedwith an inner metallic threaded member that is secured to the top openportion of the jar, after which the outer plastic member may be rotatedas desired, to force downwardly a pusher or disk piston member and itspaper-like washer contacting the viscous contents Within the jar, forexpelling same through a hollow screw stem member onto the top of theouter plastic cap. Single cap members made of plastics generally areaffected by changes of temperatures, in which they may crack or splitopen when secured tightly to the jar, hence the use of an inner metalcap member secured within a rotatable outer plastic cap member.

Another object of my invention is the advantage of my inner metalmember, that is adapted to be secured to any type of jar having lockingmeans, because of the low cost of changing the inner cap member tocorrespond to the particular locking means of any jar as plastic capswould require expensive moulds to make plastic caps to fit ontodifferent types of jars, and therefore, it is believed that my inner lowcost metal cap would .be more preferable.

A further object of my invention is that a single cap arrangement may beadopted as a much preferred form, in Which event, this cap would be ofplastic or metal, and the tubular stem and the piston member and itspaper-like washer, are operated by a knob-like portion fully rotatableon or in the crown portion of the cap secured to the jar.

For further understanding of my cap attach- :ment unit, it is applied tothe outside of a container or jar having within suitable viscouscontents, such as cold cream for example, having aflixed to it the usualcover, which is removed and discarded, and in place thereof, the innermetal cap member of my double cap attachment unit is then secured to thejar which has a downward tapering bore. Now, by simply turning the outerrotatable cap member associated with my unit, the cold cream will beexpelled through an inner tube normally sealed by a cap-stopper. Suchexpressing is achieved by having a threaded tubular stem member securedas an integral part of the outer or top cap member. The threaded tubularstem member carries a pusher member onto which is placed a paper washerhaving a yieldable periphery rim portion, so when the latter contactsthe inner tapered wall portion of the jar during rotation of the top capand extended threaded stem which forces the pusher member and paperwasher onto the cold cream, the periphery rim portion of the paperWasher is also forced down into the increasingly constricted bore of thejar, and a wiping contact is obtained onto the inner face of the taperedwall portion. In other words, the periphery rim edge of the paper washerwill yield under pressure thereby curling or be compressed onto thetapered wall portion, so that all of the cold cream within the jar willbe projected and expelled upwardly through the tubular threaded stemmember to a desired height above a mound portion of the outer capmember, whereat it is readily scooped off by the ngers of the user, andwhen jar becomes empty the paper washer will remain in its wedgedposition at the bottom of the empty jar, and then the combined cap anddepressing device is reattached to another full jar of cold cream,previous to which a clean and newly fresh paper-like washer has beenattached to the underside of the disk portion of the pusher member, theprevious used paperwasher being wedged into the extreme bottom portionof the discarded jar.

Other objects of this invention will appear as the description proceedsin the following speciiication, accompanied by the annexed drawings inwhich Figure 1 is an exterior elevational View of the interchangeablecombined cap and dispenser device of my invention.

Referring .to the `dra-wings, lan outer plastic .cap .member I :isprovided `with a top crown portion 2 that may or :may not have .aibossor mound -portion lil having a ,counterbore portion Il :into which.is .tted tightly .a threaded screw-like Vstem or tubular member 5provided with .a hollow passage V4i, yall `of which are made of .anysuitable plastic, metallic, transparent vor translucent material.tubular member 5 with its stem portion may be formed integral with theouter cap member I, .but is :considered ynot practical.

Under the .outer or .upper .plastic cap meber :I is another or secondcap member 1, preferably Vmade of metal, which has a centra-1 opening 28adapted lto 'be snapped `into a vcircular` groove l.portion :9 of aninner boss portion I 0 A4of the 'outer cap member I, thereby for-ming acombined double -cap arrangement. The li-nner boss por- `tion 4.0 may ormay not be provided with -a `recessed or counterbor-ed por-tion -I 5I toreceive the collar-'boss portion I2 of a, pusher Vor piston pressureVdisk member -I3 having pointed projections 13a on the bottom thereof,onto which is mounted and secured a flexible or yielding washer-likering member I4, for example, made of paper, which may be treated withchemicals to Vmake same liquid proof, or may be untreated, in whichevent, thin waxed paper washers I4a 'may be added to prevent the -creamsoaking into 'the paper-like washer I4.

It is to be noted that the 'periphery edge por- -ftion I5 is crimped -or`formed at I6, see Figures 4 and 9, to allow same to yield in thedownward movement in the constricted bore and against the innertaper-ing wall portion IW of `a 'ja-r J, which may have reduced top rimportion, onto which is secured the inner metal cap :member 'l byscrew-.like threads, projections or as otherwise desired, .after Athe:cover C, shown in Adotdash lines in Figure 2, has been removed. Y

the illustrative view .of Figure '.2, itis obvious that when .my `capattachment unit `is being attacked to the jar J, the viscous contents'VC within the jar, fen-ter the hollow :passage *.6v of the screw-likestem member 25, in which the 4 Viscous contents may rise until itcontacts the washerI4, whereby the friction therewith will prevent thewasher and pusher member from turning when the outer plastic cap memberis slightly turned which rotates the screw-like stem member 5, therebyforcing the pusher member 1.3 and washer Id downwardly against theviscous .contents VC, `which is forced upwardly through the passage 6and outwardly onto the mound 3, clearly shown in Figure 3.

In event the viscous contents VC within the (j ar .does not i'ill thejar completely, thereby leaving a space under the washer I4 when in itsuppermost and normal position as shown in Figure 10, means may beadopted to move the pusher member I3 down until it contacts the viscouscontents VC, such as for example, by a projecting tab or lub I6, on thepusher member I3.

When the cap attachment unit AU is not in use .onto jar J, "a sealingcap 20 is placed onto the top boss or mound portion 3 which is slightlytapered, (or may be screw-threaded, if so `-desired) and a plug-like orstopper portion 2I seals the mouth opening 3 of the .discharge passage 6vwithin the screw stern 5.

The .cap attachment unit AU when attached and secured firmly to thereduced open end portion lvl of the jar J, provides aseal thereat,thereby providing three Vdistinct .sealing means for the jar and the capattachment unit, the other two sealing means being the yieldingperiphery rim portion of the washer-disk member I3 under forced pressure.onto the inner tapering wall portion IW of the jar, and the dischargeopening cap member 2li with its Aplug or stopper portion 2l into thecream discharge vopening 3 lof vthe cap attachment unit AU.

In Figure 5, an inner metal ferrule screw member 25 may be used in placeof the inner metal cap member l, which also allows the outer cap vmemberI to freely rotate, similar to the arrangement shown in Figure 3, and bythe beaded rim portion BR. of the cap l.

In Figure 6, a single cap member .Ia of any desired material, is shownwith a threaded rim TH and a reduced mound portion 3a., onto which is.secured ,a knob 3b of the extended `member sim- Vilar to the threadedstem portion `5 .of Figure 5, which vis locked and secured for example,by a lock washer of vsplit halves .secured in the counterbore portion ofthe cap member Ia or by a key :pin 5c.

An agitator 2'! may be or may not be attach- :able to and removable fromthe end portion of Vthe hollow screw-stem 5, thereby Vpreventing.clogging or jamming of the cream in the entrance space ES, `see Figure3, and assist in keeping this .space passable for the forced cream orviscous contents therethrough. However, other means may be adopted, justso it is .as .effective for the 4same purpose, The washer I4 may or maynot be cut as at v21a to allow .same to t onto agi- 'tating member 2t',as the agitator must operate in rotation beneath the washer i4 which isheld 'stationary against cream under pressure by the .disk pusher memberI3, which is held station- -ary simultaneously .by the pointed.proections 13a, or any other .suitable .means as may be `desired, orthey underside of the disk vI 3 may be perfectly smooth .as shown inFigure 4a, or may 4have ya'iile or rough nis'h to grip washer. 'Thepaper-like washer I4 may not contact the -full underside portion of .thepusher member I3, lmay t like a, ring in the shoulder portion I3c andi3d as shown in Figures 10 and 10a.

In Figure 10 a gasket-ring or resilient pistonring member 30, or thismay be the paper-like Washer I3 formed in a ring member, either of whichmay be tted into the depressed portion 3| of the pusher member I3a,which may be a stamping l3b, such as shown in Figure 10a, the collarportion l2" being threaded to suit.

In Figure 11 an exterior view shows the cap attachment unit AU securedto the jar J when not in use, and Figure 3 shows same in use, with theforced cream projecting above the mound portion 3, whereat the cream isscooped off by the fingers of the user.

In Figure 12 an illustrative view in perspective, clearly shows the capattachment unit AU being attached to a full jar of cold cream, in whichthe hollow portion 6 of the screw stem 5 may be thoroughly cleaned asshown, or may still retain cold cream from its previous cold cream jarto which it was attached.

The inner cap member 'l may have a corrugated rim portion 45e, which maybe all around as shown, or partially spaced, so in securing the cap to anew full jar, the thin rim portion of the outer cap member I may besqueezed until it contacts the corrugated portions 45o, thereby turningthreaded rim of the inner cap member 1 for securing same to the jar J,the cap 'I may or may not be provided with corrugated portions 45d, infull depth or a part thereof.

It is to be understood that similar parts in different views in drawingsmay have the same numeral primed, and the double threaded tubular stemportion may have standard V-shape threads, and any of the partshereinbefore de scribed, may be as otherwise desired, and I do not wishto confine myself to the exactness of any part or detail shown in thedrawing, and reserve the right to alter and improve same, providing samecomes within the scope of the appended claims.

It is to be further understood that the double threaded stem portion 5in which the square type of threaded and long pitch of threads, en-

ables the user to rotate the free outer cap slightly,

and also provides a neat and safe construction, is easily handled and issafe vin washing and cleaning operations, in which V-pointed threads maycut the ingers or hands. However, the V-pointed threads can be chamferedand smoothed suiiciently to make them safe also. The pitch of thethreads is a matter of adoption, but it is believed that much time issaved by the double threads, whereby a slight turn is all that isnecessary, especially among theatrical, stage or movie, actors andactresses, this saving of time is of importance.

What I claim as new and desire to secure by Letters Patent of the UnitedStates of America, is as follows:

1. A combined cap and dispensing attachment device for jars and thelike, and of the character described, comprising an upper cap memberprovided with a recessed crown portion having a counter-bored portion, athreaded hollow stem member extending therefrom, said recessed crownportion having a hole therethrough, whereat it communicates with thehollow portion of said stem member, a boss portion provided with acircular groove portion, a second cap member provided with a similarrecessed crown central opening and a flange rim portion, said centralopening of said second cap member secured rotatably in saidcircular'groove of said boss portion of said outer cap member, adisklike pusher member having a threaded collarboss portion arranged andoperative on said threaded hollow stem member, said disk-like pushermember normally positioned within the inner recessed crown portion ofsaid second cap member, with said collar-boss portion extending in saidcounterbored portion, whereby the ange rim portion of said second capmember is adapted to be attached to a jar having viscous contentstherein.
